Patient presenting with a general or visceral contraindication to intensive treatment including :
- Cardiac insufficiency defined as Left Ventricular Ejection Fraction <50% of the theoretical value
- Plasma creatinine concentration 2 times greater than the upper limit of laboratory ranges, except if related to ALL
- Aspartate aminotransferase (ASAT) or alanine aminotransferase (ALAT) levels 5 times greater than the upper limit of laboratory ranges, except if related to ALL

Eksperimentel: GRASPA 50 IU/kg
Each patient will receive GRASPA 50 IU/kg at day 3 of the induction 1 phase.
If no toxicity related to investigational product is observed and if the patient's state of health allows it, a second injection, at the identical dose, will be administered at Day 6 of Induction 2 phase.

Efficacy Primary Endpoint - Percentage of Patients Responding to Treatment
Tidsramme: 7 days after the first administration of GRASPA® during Induction 1
|
The main evaluation criterion is a composite efficacy/toxicity criterion.
Efficacy, assessed during induction 1: percentage of patients responding to treatment, i.e. with plasma Asn concentration ≤2µM (depleted), for a duration of at least 7 days after the administration of GRASPA®
|
7 days after the first administration of GRASPA® during Induction 1

Safety Endpoint - DLTs Assessed During Induction 1 and Induction 2
Tidsramme: Induction 1 and Induction 2
|
Safety: Toxicity, assessed during Induction 1 and Induction 2: according to NCI-CTCAE v3.0 August 2006, with Dose Limiting Toxicities (DLT) defined as: Grade 2 to 4 pancreatic toxicity, Grade 3 or 4 hepatic toxicity, allergic toxicity or deep cerebral thrombosis, known as potentially related to L-asparaginase; hematological toxicity defined as bone marrow blast free aplasia, 30 days following the last injection of chemotherapy, all other Grade 4 toxicities.
